Non-Shrink Precision Grout - Mapei

WHERE TO USE Recommended for grouting voids in structural elements such as: honeycombs in concrete, filling gaps in precast elements, and grouting base plates and bridge bearings. Some application examples ▪ Anchoring of mechanical plant and machinery. ▪ Anchorage of steel bolts and other metallic fixtures. ▪ Filling of rigid joints between elements in concrete and precast concrete structures. ▪ Underpinning works. ▪ Pressure grouting of concrete structures. ▪ Grouting of machine baseplates. TECHNICAL CHARACTERISTICS Mapefill GP ME is a preblended powdered grout based on high-strength cement, graded aggregates and special additives with an expansive agent formulated by the MAPEI research laboratories. When mixed with water Mapefill GP ME is transformed into a highly fluid grout without segregation, able to fill intricate spaces. Mapefill GP ME, due to its expansive agent, is characterized by a total absence of shrinkage in the plastic (ASTM C940) phase, and develops early flexural and compressive strength. If Mapefill GP ME is prepared by only adding water, it must be cured under damp conditions, in order to guarantee that the product expansive properties develop completely and correctly. Please note that, in common with all other high-quality cementitious based materials, curing of Mapefill GP ME is essential under extreme and arid climatic conditions and/or where correct or adequate curing cannot be maintained, the addition of Mapecure SRA is highly recommended in order to ensure the required properties are attained. Mapecure SRA is considered a technologically advanced additive system that has the capability of slowing down the evaporation rate of the mixing water thereby promoting the development and efficiency of the hydration process. The addition of Mapecure SRA in proportions of up to 0.25% has the ability to reduce drying shrinkage by between 20% and 50%
